Answer
I had a similar issue getting Fedora 20, Nginx, Node.js, and Ghost (blog) to work. It turns out my issue was due to SELinux.
This should solve the problem:
setsebool -P httpd_can_network_connect 1
Details
I checked for errors in the SELinux logs:
sudo cat /var/log/audit/audit.log | grep nginx | grep denied
And found that running the following commands fixed my issue:
sudo cat /var/log/audit/audit.log | grep nginx | grep denied | audit2allow -M mynginx
sudo semodule -i mynginx.pp
Option #2 (probably more secure)
setsebool -P httpd_can_network_relay 1

Problem
I am working with configuring Django project with Nginx and Gunicorn. While I am accessing my port `gunicorn mysite.wsgi:application --bind=127.0.0.1:8001` in Nginx server, I am getting the following error in my error log file; 2014/05/30 11:59:42 [crit] 4075#0: *6 connect() to 127.0.0.1:8001 failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: `"http://127.0.0.1:8001/"`, host: "localhost:8080" Below is the content of my `nginx.conf` file; ``` server { listen 8080; server_name localhost; access_log /var/log/nginx/example.log; error_log /var/log/nginx/example.error.log; location / { proxy_pass http://127.0.0.1:8001; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $http_host; } } ``` In the HTML page I am getting `502 Bad Gateway`. What mistake am I doing?
